Yes, they should be the same. Upgrade only takes place when requested
AND accepted/switched by the backend server.

[users@httpd] reverse proxying websocket connections
The documentation states:
Proxying both HTTP and websockets at the same time, where the websockets URL's
are not websocket-only or not known in advance can be done by using the
RewriteRule directive to configure the websockets proxying:
ProxyPass / http://example.com:9080/
RewriteEngine on
RewriteCond %{HTTP:Upgrade} websocket [NC]
RewriteCond %{HTTP:Connection} upgrade [NC]
RewriteRule ^/?(.*) "ws://example.com:9080/$1" [P,L]
However, I was wondering, whether the following is an equivalent directive
(just in a single line ;-)):
ProxyPass / http://example.com:9080/ upgrade=websocket
afaik the upgrade only takes place when it is requested by a header, unless
upgrade=NONE or upgrade=ANY is set.
Am I correct or are the not the same?
Cheers,
K. C.
